Pros & Cons

Pros & Cons

  • The 35 degree angle provides a wide radar zone, and object detection up to 190 metres gives you ample time to react.
  • The Signal Radar can be paired with a phone or bike computer using ANT+ or Bluetooth.
  • DayFlash mode with an 80 lumen output ensures clear daytime visibility.
  • Thanks to the battery runtime of 14 hours, the radar will not soon run out of power and, therefore, is a reliable choice for commuting or long bike rides.
  • The Signal Radar can only be attached with an elastic strap, which is a bit more vulnerable than a hard clamping band but ensures that the radar can be used on all bikes.
  • Some users may find the sound signals unnecessary.

5 / 5

Very good site with the material available free 4-day delivery

- Patrick 17 February 2026

The radar is bright several functions but I prefer radar only and it flashes when a car arrives, you can cut if you want the speaker function, for the moment I use it with hspeaker because my meter is not recent enough to integrate the visual, but I lent it and works very well on a recent meter.
